Do You Know About Light And Reflection? Quiz - Quiz

Light is a form of energy usually in the form of electromagnetic radiation that travels by way of waves within a specific portion of the electromagnetic spectrum. Reflection generally is when a traveling wave bends toward another direction because of its contact with a shiny or reflective surface. Try to ace this quiz.
